HANDLE FOR SCREW-DRIVERS AND OTHER TOOLS.

SPECIFICATION forming part of Letters Patent No.354,359, dated December 14., 1886.

Application tiled August 21, 1886.

To @ZZ whom, it may concern,.-

Beit known that I, JAMEs G. SPENCER, a citizen of the United States, residing at Rochester, inthe county of Monroe and State of New York, have invented certain new and useful Improvements in Handles for Screw- Drivers and other Tools, of which the following is aspecification, reference being had therein to the accompanying drawings.

My invention relates to improvements in devices to rotate screw-drivers, hand-drills, bits, angers, &c.; and the objects of my improvements are to provide a handle through which .y various tools may be rotated at will, either in one direction only or intermittently in opposite directions, according to the location of a nut upon oneend of the spindle of the tool, or upon its support, and the location of the members of a clutch at the opposite end. I accomplish these objects bythe construction illustrated in the accompanying drawings, in

' which- Figure l represents a longitudinal section of a tool constructed in accordance with my invention. Figs. 2 and 3 are longitudinal sections ot' modications of the same. Fig. 4 represents in side view the clutch at one end of the tool provided with a tapering bit, as a screw-driver; and Fig. 5 represents the same .end provided with a socket to receive various tools. b

In the drawings, A represents the spindle to be rotated, and having close .to its lower end one member, c, of a clutch having its upper surface provided with inclined teeth. Surrounding the spindle is a tube, B, carrying at its lower end the member b of a clutch having inclined teeth made to engage with the teeth of the member a. The tube B has coiled upon its surface a worm, b2, to rotate it by means of the hand-nut O, placed thereon, while the latter is moved up and down along the surface of the tube and its worm. To cause the spindle to he rotatedubacl; and forth while the hand-nut is moved up and down, a nut, D, is made to rest upon the upper end of the tube B, to retain the teeth of the two members a b of the clutch interlocked and united; but when itis desired to have the 5o tool at the lower end of the device rotate in one direction only-as, for example, when a screw-driver, A', or an auger is used therewith-the clutch members are permitted to Serial No. 211,526. (No model.)

be disconnected by running up the nut D a short distance upon its screw-threaded stem, and thus permitting the tube B to revolve freely upon its spindle, 'while the hand-nut O is made to travel upward upon said tube; but when the hand-nut is again made to travel away from the upper handle, E, the first part 6c of the motion of said hand-nut unites the members of the clutch and causes the spindle A to revolve with the tube B.

Various means may be used to connect the screw threaded stem e of the nut D with the handle. In Fig. l the screw-threaded stem e is made to enter a cap, e?, and it may be made integral therewith, and the cap e2, after being driven iutothe handle E, may be retainedimmovabl y connected therewith by a pin,e, pass- 7o ing through the upper end of said'cap and through thehandle,or by other suitable means. In said Fig. l the upper end of the spindle A has a collar, a2, that rests against the upper end of the screw-threaded spindle and prevents the withdrawal of the spindle A. In Fig. 3 the cap e2 is dispensed with, and the screw-threaded stem e is screwed directly into the handle E, and the withdrawal ofthe spindle A is prevented by a pin, e, passing trans- So versel y through the handle and engaging with a collar on said spindle. In Fig. 2 the nut I) is made to engage with screw-threads'cut upon the spindle A, and the upper end of said threads is made conical, or provided with a collar to abut against the lower end of the handle, while the upper end of the spindle is provided with a washer', f, and is riveted thereon to retain it connected with the handle.

Having now fully described my'invcntion, go I claim- A tool-handle consisting of a spindle, atube inelosing it, a spiral worm upon said tube,and a hand-nut upon the tube and worm, with the membersof a clutch upon one end of thespin- 93 dle and upon one end of the tube, and a nut, D, adapted to bear upon the opposite end of the tube, substantially as and for the purpose described.

In testimony whercofl aiix my signaturein roo presence of two witnesses.
